My Mac Build doesn't work when I try to open it

I just started using unity and i'm trying to understand how the whole thing works, so i followed the tutorials and made a very simple game (my first, never did before) and the simulation on unity went fine, but then after i build it the application doesn't open, showing the window that says "the application quit unexpectedly". How can I fix this? It's a permission problem or something else?
